Teeth are the gatekeepers, the flourishing aspect of the Kidney, and the remainder of the bones. When Kidney qi declines, teeth become loose and fall out; when essence is secure, teeth remain firm. Additionally, collateral branches of the Large Intestine distribute to the gums, primarily irrigating the teeth. If the Large Intestine is obstructed, teeth become floating; if deficient, roots are exposed; if complicated by wind, the condition attacks the eyes and face; if complicated by childhood malnutrition (Gan syndrome), teeth decay and fall out, leading to hemorrhoids. All these arise from qi stagnation. Although the syndromes differ, treatments vary by formula. An Shen Wan (Kidney-Anchoring Pill) and Ba Wei Wan (Eight-Ingredient Pill) both treat toothache, swelling, and edema caused by deficiency and obstruction.
An Shen Wan See the section on Lower Back Pain for the formula.
Ba Wei Wan See the section on Beriberi/Jiaogiqi for the formula.
